Additional high-speed lines [edit] Honam HSR [modify] Until 2006, the very first prepare for a 2nd, separate high-speed line from Seoul to Mokpo were developed into the task of a line branching from the Gyeongbu HSR and built in 2 phases, the Honam High Speed Train (Honam HSR). The budget for the 185.
42 mi) very first phase, from the brand-new Osong Station on the Gyongbu HSR to Gwangju, Songjeong Station, was set at 8,569. 5 billion won. The 2nd phase, the 48. 74 km (30. 29 mi) staying to Mokpo, was to be ended up by 2017 with a budget of 2,002. 2 billion won.
The ground-breaking event was held on December 4, 2009. Since September 2010, progress was 9. 6% of the project budget then estimated at 10,490. 1 billion won for the very first phase, which was due for completion in 2014, while the estimate for the entire line stood at 12,101. 7 billion won.
The branch to Suseo was re-launched as a different project, the Suseo High Speed Railway (Suseo HSR), in June 2008. Comprehensive style of the 61. 1 km (38. 0 mi) line is underway given that September 2010, with opening planned by the end of 2014. For the longer term, new high-speed lines from Seoul to Sokcho on the eastern coast, and a direct branch from the Gyeongbu HSR south to Jinju and even more to the coast are under factor to consider.
Jeju Island [modify] In January 2009, the Korea Transportation Institute also proposed a 167 km (104 mi) line from Mokpo to Jeju Island, putting Jeju 2 hours 26 minutes from Seoul. Key Reference would consist of a 28 km (17 mi) bridge from Haenam to Bogil Island and a 73 km (45 mi) undersea tunnel from Bogil Island to Jeju Island (with a drilling station on Chuja Island), for an approximated cost of US$ 10 billion.
